Ion pump (physics)

We have a dab-link to it, but it doesn't exist. D'oh:( DMacks 02:33, 2 November 2006 (UTC)

Ion pump (physics) was delested for copyright violation:

Move

I propose that we move this page to Ion transporter. I'll do this move myself in a couple days if no one objects. delldot | talk 07:02, 9 January 2007 (UTC)

Well, no one objected, so I'm going to move it. We can discuss it or move it back later if necessary. delldot | talk 01:39, 16 January 2007 (UTC)

ion pump and ion transporter is not the same

ion pump create a gradient of ions and the transporter only tranport ions —Preceding unsigned comment added by 190.22.185.13 (talk) 13:28, 16 November 2008 (UTC)

I agree with the editor from 190.22.185.13. "In biology, an ion transporter, also called an ion pump" The term "ion transporter" is not synonymous with "ion pump". Maybe this page should be reconstructed as a page for Primary Active Transporters. --IONTRANSP (talk) 19:11, 17 July 2012 (UTC)

I'm not disagreeing - but this is rather confusing.. Can someone find a citation for what the actual distinction between the two is - even if the distinction is not "properly" respected by some (or most?) of the literature. Does the first comment (ion pump create a gradient of ions .. transporter only transport ions) mean that a pump is a term used for a specialized function of a transporter? (Of course, I'm still inwardly grumbling about the lack of much of any kind of literature to figure out whether Gilbert Ling is or is not a total crack-pot.. See the seeming sole example, and article by Edelman ["Doubts about the sodium-potassium pump are not permissible in modern bioscience" (2005), PMID 16359622 {{citation}}: Missing or empty |title= (help)]). (... Oops, forgot to sign this post.. auto-sign bot perhaps?) Jimw338 (talk) 19:02, 7 September 2012 (UTC)

"Can someone find a citation" <-- There are several online textbooks that describe the distinction between the different types of membrane transport proteins: Lodish textbook, Cooper textbook, Alberts textbook, Stryer textbook, Albers textbook.

"...pump is a term used for a specialized function of a transporter?" <-- Only some membrane transport proteins function as "pumps". In general, a pump protein can use a source of energy (from a chemical bond or absorbed photon) to move a substance across a cell membrane in the direction that is opposite from the direction that the pumped substance would normally move if moving by only spontaneous molecular motions.

Off topic: Gilbert Ling. Do you have a copy of Edelman's article? Are you primarily interested in his ideas about the organization of water inside cells or something else? We can discuss this on my user talk page. --IONTRANSP (talk) 20:02, 13 September 2012 (UTC)

Off topic: I am thinking of adding a section about how these transporters are studied, including methods such as voltage clamp, patch clamp, lipid bilayer assay, and radioactive labeling. I am also looking at changing the first sentence from " transmembrane protein to ion channel as it is a more specific description and the link to the ion channel page would be more beneficial than a link to the transmembrane protein page. Please let me know if there are other techniques y'all are aware of. Jimmyjohnslaser (talk) 03:50, 6 October 2020 (UTC)
